immunogenesi
Immunogenesis, or the generation of an immune response, is the collective process by which an organism recognizes an antigen and mounts an adaptive immune reaction. The term covers the sequence from initial antigen recognition and innate sensing to the activation and differentiation of antigen-specific lymphocytes, formation of effector cells that eliminate the threat, and the development of immunological memory that provides future protection.
Key events include antigen presentation and co-stimulation. Dendritic cells and other antigen-presenting cells capture foreign material,
Effector responses follow: cytotoxic T cells destroy infected cells; helper T cells coordinate responses; plasma cells
Factors that influence immunogenesis include intrinsic properties of the immunogen, such as size, complexity, epitope density,
